2009-02-27Fix recursive lock in free_uid()/free_user_ns()David Howells
free_uid() and free_user_ns() are corecursive when CONFIG_USER_SCHED=n, but free_user_ns() is called from free_uid() by way of uid_hash_remove(), which requires uidhash_lock to be held. free_user_ns() then calls free_uid() to complete the destruction. Fix this by deferring the destruction of the user_namespace.

2009-02-27cfg80211: Add AP beacon regulatory hintsLuis R. Rodriguez
When devices are world roaming they cannot beacon or do active scan on 5 GHz or on channels 12, 13 and 14 on the 2 GHz band. Although we have a good regulatory API some cards may _always_ world roam, this is also true when a system does not have CRDA present. Devices doing world roaming can still passive scan, if they find a beacon from an AP on one of the world roaming frequencies we make the assumption we can do the same and we also remove the passive scan requirement. This adds support for providing beacon regulatory hints based on scans. This works for devices that do either hardware or software scanning. If a channel has not yet been marked as having had a beacon present on it we queue the beacon hint processing into the workqueue. All wireless devices will benefit from beacon regulatory hints from any wireless device on a system including new devices connected to the system at a later time. Signed-off-by: Luis R.

2009-02-27mac80211: Extend the rate control API with an update callbackSujith
The AP can switch dynamically between 20/40 Mhz channel width, in which case we switch the local operating channel, but the rate control algorithm is not notified. This patch adds a new callback to indicate such changes to the RC algorithm. Currently, HT channel width change is notified, but this callback can be used to indicate any new requirements that might come up later on.

2009-02-27mac80211: fix aggregation for hardware with ampdu queuesJohannes Berg
Hardware with AMPDU queues currently has broken aggregation. This patch fixes it by making all A-MPDUs go over the regular AC queues, but keeping track of the hardware queues in mac80211. As a first rough version, it actually stops the AC queue for extended periods of time, which can be removed by adding buffering internal to mac80211, but is currently not a huge problem because people rarely use multiple TIDs that are in the same AC (and iwlwifi currently doesn't operate as AP). This is a short-term fix, my current medium-term plan, which I hope to execute soon as well, but am not sure can finish before .30, looks like this: 1) rework the internal queuing layer in mac80211 that we use for fragments if the driver stopped queue in the middle of a fragmented frame to be able to queue more frames at once (rather than just a single frame with its fragments) 2) instead of stopping the entire AC queue, queue up the frames in a per-station/per-TID queue during aggregation session initiation, when the session has come up take all those frames and put them onto the queue from 1) 3) push the ampdu queue layer abstraction this patch introduces in mac80211 into the driver, and remove the virtual queue stuff from mac80211 again This plan will probably also affect ath9k in that mac80211 queues the frames instead of passing them down, even when there are no ampdu queues.

2009-02-27Bluetooth: Ask upper layers for HCI disconnect reasonMarcel Holtmann
Some of the qualification tests demand that in case of failures in L2CAP the HCI disconnect should indicate a reason why L2CAP fails. This is a bluntly layer violation since multiple L2CAP connections could be using the same ACL and thus forcing a disconnect reason is not a good idea. To comply with the Bluetooth test specification, the disconnect reason is now stored in the L2CAP connection structure and every time a new L2CAP channel is added it will set back to its default. So only in the case where the L2CAP channel with the disconnect reason is really the last one, it will propagated to the HCI layer. The HCI layer has been extended with a disconnect indication that allows it to ask upper layers for a disconnect reason. The upper layer must not support this callback and in that case it will nicely default to the existing behavior. If an upper layer like L2CAP can provide a disconnect reason that one will be used to disconnect the ACL or SCO link. No modification to the ACL disconnect timeout have been made. So in case of Linux to Linux connection the initiator will disconnect the ACL link before the acceptor side can signal the specific disconnect reason. That is perfectly fine since Linux doesn't make use of this value anyway. The L2CAP layer has a perfect valid error code for rejecting connection due to a security violation. It is unclear why the Bluetooth specification insists on having specific HCI disconnect reason. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Add CID field to L2CAP socket address structureMarcel Holtmann
In preparation for L2CAP fixed channel support, the CID value of a L2CAP connection needs to be accessible via the socket interface. The CID is the connection identifier and exists as source and destination value. So extend the L2CAP socket address structure with this field and change getsockname() and getpeername() to fill it in. The bind() and connect() functions have been modified to handle L2CAP socket address structures of variable sizes. This makes them future proof if additional fields need to be added.

2009-02-27Bluetooth: Request L2CAP fixed channel list if availableMarcel Holtmann
If the extended features mask indicates support for fixed channels, request the list of available fixed channels. This also enables the fixed channel features bit so remote implementations can request information about it. Currently only the signal channel will be listed. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Don't enforce authentication for L2CAP PSM 1 and 3Marcel Holtmann
The recommendation for the L2CAP PSM 1 (SDP) is to not use any kind of authentication or encryption. So don't trigger authentication for incoming and outgoing SDP connections. For L2CAP PSM 3 (RFCOMM) there is no clear requirement, but with Bluetooth 2.1 the initiator is required to enable authentication and encryption first and this gets enforced. So there is no need to trigger an additional authentication step. The RFCOMM service security will make sure that a secure enough link key is present. When the encryption gets enabled after the SDP connection setup, then switch the security level from SDP to low security. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Fix double L2CAP connection requestMarcel Holtmann
If the remote L2CAP server uses authentication pending stage and encryption is enabled it can happen that a L2CAP connection request is sent twice due to a race condition in the connection state machine. When the remote side indicates any kind of connection pending, then track this state and skip sending of L2CAP commands for this period. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Fix race condition with L2CAP information requestMarcel Holtmann
When two L2CAP connections are requested quickly after the ACL link has been established there exists a window for a race condition where a connection request is sent before the information response has been received. Any connection request should only be sent after an exchange of the extended features mask has been finished. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Use general bonding whenever possibleMarcel Holtmann
When receiving incoming connection to specific services, always use general bonding. This ensures that the link key gets stored and can be used for further authentications. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Add SCO fallback for eSCO connection attemptsMarcel Holtmann
When attempting to setup eSCO connections it can happen that some link manager implementations fail to properly negotiate the eSCO parameters and thus fail the eSCO setup. Normally the link manager is responsible for the negotiation of the parameters and actually fallback to SCO if no agreement can be reached. In cases where the link manager is just too stupid, then at least try to establish a SCO link if eSCO fails. For the Bluetooth devices with EDR support this includes handling packet types of EDR basebands. This is particular tricky since for the EDR the logic of enabling/disabling one specific packet type is turned around. This fix contains an extra bitmask to disable eSCO EDR packet when trying to fallback to a SCO connection. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Pause RFCOMM TX when encryption dropsMarcel Holtmann
A role switch with devices following the Bluetooth pre-2.1 standards or without Encryption Pause and Resume support is not possible if encryption is enabled. Most newer headsets require the role switch, but also require that the connection is encrypted. For connections with a high security mode setting, the link will be immediately dropped. When the connection uses medium security mode setting, then a grace period is introduced where the TX is halted and the remote device gets a change to re-enable encryption after the role switch. If not re-enabled the link will be dropped. Based on initial work by Ville Tervo <ville.tervo@nokia.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2009-02-27Bluetooth: Add enhanced security model for Simple PairingMarcel Holtmann
The current security model is based around the flags AUTH, ENCRYPT and SECURE. Starting with support for the Bluetooth 2.1 specification this is no longer sufficient. The different security levels are now defined as SDP, LOW, MEDIUM and SECURE. Previously it was possible to set each security independently, but this actually doesn't make a lot of sense. For Bluetooth the encryption depends on a previous successful authentication. Also you can only update your existing link key if you successfully created at least one before. And of course the update of link keys without having proper encryption in place is a security issue. The new security levels from the Bluetooth 2.1 specification are now used internally. All old settings are mapped to the new values and this way it ensures that old applications still work. The only limitation is that it is no longer possible to set authentication without also enabling encryption. No application should have done this anyway since this is actually a security issue. Without encryption the integrity of the authentication can't be guaranteed. As default for a new L2CAP or RFCOMM connection, the LOW security level is used. The only exception here are the service discovery sessions on PSM 1 where SDP level is used. To have similar security strength as with a Bluetooth 2.0 and before combination key, the MEDIUM level should be used. This is according to the Bluetooth specification. The MEDIUM level will not require any kind of man-in-the-middle (MITM) protection. Only the HIGH security level will require this. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Add support for deferring RFCOMM connection setupMarcel Holtmann
In order to decide if listening RFCOMM sockets should be accept()ed the BD_ADDR of the remote device needs to be known. This patch adds a socket option which defines a timeout for deferring the actual connection setup. The connection setup is done after reading from the socket for the first time. Until then writing to the socket returns ENOTCONN. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Add global deferred socket parameterMarcel Holtmann
The L2CAP and RFCOMM applications require support for authorization and the ability of rejecting incoming connection requests. The socket interface is not really able to support this. This patch does the ground work for a socket option to defer connection setup. Setting this option allows calling of accept() and then the first read() will trigger the final connection setup. Calling close() would reject the connection. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2009-02-24netlink: change nlmsg_notify() return value logicPablo Neira Ayuso
This patch changes the return value of nlmsg_notify() as follows: If NETLINK_BROADCAST_ERROR is set by any of the listeners and an error in the delivery happened, return the broadcast error; else if there are no listeners apart from the socket that requested a change with the echo flag, return the result of the unicast notification. Thus, with this patch, the unicast notification is handled in the same way of a broadcast listener that has set the NETLINK_BROADCAST_ERROR socket flag. This patch is useful in case that the caller of nlmsg_notify() wants to know the result of the delivery of a netlink notification (including the broadcast delivery) and take any action in case that the delivery failed. For example, ctnetlink can drop packets if the event delivery failed to provide reliable logging and state-synchronization at the cost of dropping packets. This patch also modifies the rtnetlink code to ignore the return value of rtnl_notify() in all callers. The function rtnl_notify() (before this patch) returned the error of the unicast notification which makes rtnl_set_sk_err() reports errors to all listeners. This is not of any help since the origin of the change (the socket that requested the echoing) notices the ENOBUFS error if the notification fails and should resync itself.

2009-02-22netns: Remove net_aliveEric W. Biederman
It turns out that net_alive is unnecessary, and the original problem that led to it being added was simply that the icmp code thought it was a network device and wound up being unable to handle packets while there were still packets in the network namespace. Now that icmp and tcp have been fixed to properly register themselves this problem is no longer present and we have a stronger guarantee that packets will not arrive in a network namespace then that provided by net_alive in netif_receive_skb. So remove net_alive allowing packet reception run a little faster. Additionally document the strong reason why network namespace cleanup is safe so that if something happens again someone else will have a chance of figuring it out. Signed-off-by: Eric W.

2009-02-22PM: Split up sysdev_[suspend|resume] from device_power_[down|up]Rafael J. Wysocki
Move the sysdev_suspend/resume from the callee to the callers, with no real change in semantics, so that we can rework the disabling of interrupts during suspend/hibernation. This is based on an earlier patch from Linus. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
